You need sound flower and LineIn for this to keep Rosetta Stone from changing the Sample Rate of your USB Headset to 16kHz. In LineIn make the input from field your USB Microphone then make the output to Sound Flower 2ch then select Pass Thru. In both the Sound Flower and USB setting in the Utility Audio MIDI setup make sure that everything is 44.1kHz Make sure Rosetta stone is pointed to Sound Flower 2ch.

You sound output can remain the USB Headset. The software bug is Rosetta Stone changing the input to 16kHz and then Rosetta Stone does nothing after that. Sound flower and LineIn run interference to keep it from doing that

Worked for me!
good luck!

I downloaded Soundflower but it doesn't seem to work with Lion??

Anyone got a workaround to get a mic either internal or external to show in Rosetta Stone Version 3 with Lion please? Its still greyed out in the Rosetta Stone software but the external mic definitely works in Skype.

Hi,
Some of you are discussing a problem where your microphones are no longer visible in the list of microphones after upgrading to OS 10.7. At least in my case I was able to upgrade to the most current version of rosetta stone and my microphones are now listed and work fine. I was at V3.4.5 of the Rosetta Stone, here is the link :

I upgraded to Lion a few weeks ago and a friend gave me her Rosetta Stone program to learn French. It was an older version 3.3.7. I was having the same mic problems with RS not even seeing the microphone. I tried setting the sound to line-in and volume at half but it didn't work.

Then I upgraded to 3.4.5 and it fixed everything. RS is MUCH better with speech recognition. Only thing is I have to go back and repeat some of the lessons C'est la vie!

Anyone got a workaround to get a mic either internal or external to show in Rosetta Stone Version 3 with Lion please? Its still greyed out in the Rosetta Stone software but the external mic definitely works in Skype.

Thanks

M Lococo's fix is working fine for me, though it took a little jiggling.

With this Ap open, one can choose to use for the output: SunFlower 2ch
for the USB mike Input on my System: AK5 370
and 44100 Hz

I was having trouble with opening RS 3.4.5 (using lion). I kept getting the "PPC apps are no longer supported" message. So I right clicked rosetta stone, clicked "show package contents", then went to Contents>MacOS> and opened 'Rosetta Stone" if you open this executable RS works fine... Not sure why, but now I'm learning German!

Hey guys, if you have trouble with rosettastone not recognizing your microphone, and you are stuck, here is the solution:
Install parallels, install a copy of windows xp, and then install rosettastone in the windows operating system, not on the mac.
It will recognize the headset and any kind of mic and it will work like a charm. Worked great for me.

OK, I have the new 15" retina display macbook pro running 10.8.2
I installed a "gifted" copy of Rosetta Stone v3.4.5 for MAC
When I set up the program there were no Microphones to choose from. I tried everything, sound flower, Linein, I set it up to the 44.4 hz thingie, and pointed it to my logitech h540 USB headset. And this might have all worked except....I had done one last thing before I had set up the sound flower....I went to the Rosetta Stone support page and found an update that they had recently released. I was afraid at first to do the update, because I was afraid it would mess up my 'gifted' copy of Rosetta stone, (I didn't have an activated version) . But, what the hey..I tried to download it and it installed. Now, I had soundflower, and linein all set up...my headphones were plugged in, the update was downloaded...time to reboot...I did so and
Voilà! Suddenly Rosetta saw my internal microphone and the Soundflower Ch2 and Ch64. I chose CH2, as suggested above...set up the microphone 1,2,3,4,5... and it worked! Except the sound was going in through the Logitech and out through the computer.

So, I deleted Soundflower..and Linein...unplugged my Logitech headset...reset my microphone in Rosetta to Internal Microphone...then went back to my computer Sound Setup and made sure everything there was pointing to the internal microphone......Back to Rosetta, and I was up and running. Next I plugged in a set of Apple earbuds...from my old iphone 4s...and the whole thing WORKS! yeah!!

Bottom line...skip the Soundflower and Linein...and just install the little update for version 3...even if you have a 'gifted' copy...

Here is the link for the download for the MAC update for Rosetta V3 or V3.4.5

and once there I followed a post that advised the following update. Version 3 updated to 3.4.5. All my user progress was unaffected. The microphone worked just fine after this. I was having the same problem that everyone else had. I had Version 3 of Rosetta Stone but had upgraded to Mac OS Lion 10.7.5 and no microphone was recognized despite functionality in preferences. Here is the link for the auto dmg-download upgrade:
